A Study to Compare Zavegepant Concentration Using Samples Collected From the Vein Versus Patient-Centric Microsampling

United States14 participantsStarted 2023-07-10

Plain-language summary

The purpose of this clinical trial is to learn about the pharmacokinetics and safety of a drug called zavegepant from samples collected using a patient-centric device called Tasso-Plus (for liquid blood sample collection) and Tasso-M20 (for dried blood sample collection) compared to standard venous sample collection. This study consists of two periods and will enroll approximately 14 healthy participants. In period 1, half of the enrolled participants (n=7) will use Tasso-Plus, and the other 50% (n=7) will use Tasso-M20. For each participant, PK samples will be collected after zavegepant administration in period 1 using the assigned Tasso device simultaneously with collecting venous blood samples. In addition, taste assessments will be performed at time intervals of 1 (immediately after dosing), 5, 10 and 20 minutes after zavegepant IN administration. Also, if feasible, 4 Japanese participants will be enrolled among those 14 participants to evaluate the PK and safety of zavegepant IN in Japanese vs. non Japanese participants. In period 2, a butterscotch candy will be given 5 minutes before administering the zavegepant IN study intervention. Taste assessment will also be performed after zavegepant IN administration with a butterscotch candy in period 2. For taste assessment, each participant will record the sensory attributes at timed intervals of 1 (immediately after dosing), 5, 10 and 20 minutes after zavegepant administration in each period. The expected duration of participation from screening until follow-up telephone contact is approximately 9 weeks.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
